The memory region size ( also called logical memory block ( LMB ) size ) must be the same on the source and destination systems. 源系统和目标系统的内存区域大小,也称为逻辑内存块(LMB)(LMB)大小,必须相同。
We propose that the memory block is divided into a number of logical partitions, and then every iteration whole only one logical partition of memory block is replaced. 为减少磁盘I/O,本文提出将存贮表在内存中的数据块划分为若干逻辑分区,每次连接计算后仅替换其中的一个逻辑分区。
